Birmingham And Leeds Bradford - X-winds
Both DUBLIN and SHANNON have WSW winds gusting to 50kts. This represents 40 degrees left of Dublin's Rwy 28.
BIRMINGHAM (BHX) and LEEDS BRADFORD (LBA) appear to be the most cross-windy of the large airfields in the UK, at the time of writing, with their north-westerly runways.
The LEEDS BRADFORD TAF (see below) suggests that there will be problems for ops on Rwy 32 (the only one available) from 0300z to 1800z tomorrow (Wednesday). It is currently over 30kts component in gusts (see below).

BIRMINGHAM is already getting a crosswind component of 35kts in gusts, on Rwy 33. [Rwy 24 is only about 1200m long.] The latest 24-hr TAF (see below) has increased the wind strengths for tomorrow. The wind is now forecast to be we outside some crosswind limits, occasionally, between 0500z and 1100z tomorrow (Wednesday).

London Heathrow - No forecast problems?
Selection of METARS, and the current TAFs for LONDON HEATHROW [NB: most recent now at the top.]
The mini-ridge of (relatively!) high pressure provided an overnight lull of moderate westerlies, but is now history. The QNH peaked at 988 at LHR between 0720z and 1020z, with the W/V backing/reducing to 210/12. The warm front/occlusion associated with the next system arrived around midday. The marked rise in dew-point was reversed as a further trough (?) transited at about 1400z, with showery outbreaks. Since then the pressure has recovered slightly, but the wind has strengthened/veered to nearly gale-force westerly (260/29-41 at 1550z).

Its all part of dumbing down - when's the last time you saw a synoptic chart on the BBC?

Possibly been discussed to death already but just how bad is the internet in affecting flight deck decisions?
When we arrived at AMS today the wind was 240/25G32. There were long delays for 27 whereas 18R was wide open.
I can understand a few of the heavies having flown all night over the atlantic maybe opting for a delay, but for all the rest, is fear of pprune / youtube really that bad?
Tomorrow should be fun...
There was an American who said on the RT that he didn't want to end up on You tube so I think he diverted to AMS!

Often wondered...?
Wonder whether Chris or anyone else could explain what the "corrected" means for LHR. How come only London ever needs correcting on the Volmet? Can't think I've heard it used on any other volmet in Europe...

Corrected metar
MAN is another one that is regularly given as corrected. Not 100% sure of the reason, could it be that the data is gathered automatically rather than by human hand and is then adjusted before transmission?

Sorry for the slight thread drift but for those of you scoffing at what you consider to be the overly dramatic news coverage of Mondays storm, then maybe you would like to see the following. These are the scenes that met me when I finally made it home from EDI. I think you'll agree, they are quite shocking!

Now back to the thread and the next, fast approaching weather front.... From what I've seen, it's not gonna make it further south than the M25 so there's nothing to worry about then!
P.S. No ducks were harmed in the making of this film.

Sorry for the simple SLF questions & possible thread drift, but would the windspeed at AMS last night be sufficient to reduce a/c groundspeed by a noticable margin?
[Unquote]
Surface W/V at 1955Z was 160/22-32. Schiphol area is very smooth, but – on the other hand – it was night-time, so you’d expect some nocturnal windshear, perhaps. My guess would be that the wind at 500ft would be about 180/40+. So the GS could be noticeably low on approach Rwy 18R.

FCUK12 tells us [thanks...] that the 2-hr Trend Forecasts, still appended to some airfields like LHR, are prepared at the Met Office in EXETER (like the TAFs). The observer (ATCO?) is obviously not qualified to do it.
Think what probably happens sometimes is that the METAR is broadcast before the system has tacked the TREND on to the end of it. When the omission comes to someone’s attention, the METAR has to be reissued as a “COR!”.

Yes, BBC wants to use my involuntary licence fee to perpetuate the chattering-class prejudice that science and maths are fringe topics, that rarely justify inclusion in their output. And, when they have to be covered, they are generally presented in an increasingly apologetic and infantile style.

SLF having fun
Just landed at Dublin in the Saab Loganair from City of Derry airport. After reading the METAR I can imagine that the aircraft was close to the limits (maybe someone can confirm).
Personally I had a great time and enjoyed being thrown around. Person behind me was terrified of flying. Crew did a great job of making sure she was happy.
Yesterday morning I flew Newcastle to Belfast as SLF. Quite an impressive site seeing the cloud clear overhead IOM. Landing with blue sky and light breeze.
Personally I think the media are short on stories. Nothing that different compared to previous systems that have come in from the Atlantic. I guess the forcasted low pressure got people excited.
Anyway - SLF tomorrow morning to Brussels from Dublin

Suggs,
The ICAO wind is the standard wind reading you are given.
It is the 2 min average including any gusts (greater than 10 kts above the average) in the last 10 mins.
Gatwick were passing both the ICAO and instant a lot yesterday because a lot of a/c were requesting the instant wind.

The 65-knot gust is only a 30% probability, so all book-Nigels would ignore it for planning purposes, OFFICIALLY.
Think Rwy 23's bearing is 223(T)? If the wind veered (in the gust) to - say - 263/65, that would give a crosswind component of about 40kts. Probably won't happen.

The 65-knot gust is only a 30% probability, so all book-Nigels would ignore it for planning purposes, OFFICIALLY.
Think Rwy 23's bearing is 223(T)? If the wind veered (in the gust) to - say - 263/65, that would give a crosswind component of about 40kts. Probably won't happen.

Marvellous - I finally get around to doing my IR (due tomorrow!) and along comes the worst storm for what?...almost 20 years?!!! I think a delay to Friday is on the cards! Incidentally, for those that know, AFT is as priceless as ever!

Just got word that LPL is about to close due to the wind. Got an FCA stuck there trying to get down to BHX but we've an x-wind of 24G36 at the moment with severe turbulence in the TDZ due to the hangers
